This class provides a project-based exercise in the engineering design
process. Students work in teams and as individuals on defined projects
which utilize knowledge and skills in graphics, statics, computing,
and mechanics of materials. The projects encompass conceptual design,
detailed analysis, engineering drawings, experimentation, physical model
fabrication, laboratory testing, and preparation of professional reports.

Collaboration Policy

Project work is normally done in groups of two (1 hand-in
per group). Each group must do their own work, however, general discussion
of the project is encouraged. If you put your name on it, it must be
your work.

Reference vs. Plagiarism

You may use materials from a book or another source as
reference, if you do so you must properly cite the source. Failure to
do so is plagiarism and will result in failure. If it is not your work,
you have to say so. Information from www sources is unacceptable as
references.

Supplemental Exam

There is no final or midterm, students are graded based
on their work during the term. Since there is no final exam in this
course, no supplemental exam is offered.

Each year students will build a device to perform a defined task. A
final report and a working device will be due at the end of term. A
contest will be held in the last week of classes.

This year the contest is to design a ``Ping-Pong Ball Snowplow''

CONTEST RULES

The device will be placed in a 4'x 8' field of ping-pong balls.
The device must pick up as many ping pong balls as possible within 30
seconds.

Teams will compete head to head, two teams starting simultaneously.

Contestants will have 1 minute before each match to prepare/repair
their devices.
Late devices will be disqualified.

Devices must be powered and operated from external control boxes.
The control boxes will be provided:
3 volts from two AA cells (student supplied)
via two DPDT switches (+/-),
to 4 wire telephone cord umbilicals.

Devices will be shut off after 30 seconds and balls counted.
Devices continuing after 30 seconds will be penalized/disqualified.

A ball is picked up if it does not touch the floor and is 50% within
the device.

Devices are allowed to interfere with (not destroy) their opponents.

The assembled device must be able to fit within a milk crate ( 11"x12"x12").

Devices must start within a 12"x12" square.

Only materials found in the standard supply kit may be used.

The device must be safe and must pass inspection.
Students must wear eye protection during operation.

Any rotating/moving parts must not be a hazard.
Operators must be able to turn the device on and off without injury.

The contest ping pong balls may not be permanently altered or damaged
in any way.
The contest arena may not be permanently altered or damaged in any way.

Judges decisions are final.
Any device breaking the rules will be impounded and will not compete
in the contest.

You bend the rules at your own risk.
You may decide to interpret the rules creatively, but you must check
the legality first.

The Contest

All teams will compete at least twice.

Teams will be sorted by the number of wins and then by ball count.
The best 8 teams after two rounds will enter single elimination playoffs,
with the winner of each trial continuing to next round.
For example: quarter-finals (8 teams), semi-finals (4 teams), final
(2 teams)

Design projects will be evaluated on the basis of several factors:
- Quality, originality and efficiency of the design
- Written final report
- Construction of the device
- Performance of the device

Note that the winner of the contest will not necessarily get the highest
mark.
Nor does a poor showing in the contest necessarily mean a low mark.

Safety Rules

All students must obey all safety rules at all times.
Failure to follow these rules will result in failure.
Testing is to be done in designated testing area only.

Students must wear eye protection during operation.

Devices will be inspected a few days prior to the contest.
Teams that do not pass inspection will not compete in the contest.

MECH 2100 Projects are to be done in groups of two, 1 hand-in per group.

The following MINIMUM standards will be adopted for all reports.

1.
Reports will be submitted on 8 1/2" by 11" unlined white paper.

2.
The DATE, COURSE NAME, COURSE NUMBER, REPORT NAME
and your NAMES must be neatly lettered on a title page.
Other pages will be numbered.

3.
Reports are to be done on the front side of the pages only, do not use
the backsides of the pages.

4.
Reports must be bound together.

5.
All text must be typewritten, handwritten text is unacceptable.

6.
All sketches and figures must be neat.
2D figures should be machine drawn, initial and 3D sketches may be hand
drawn in ink.
Graphs must be labeled with scales and units for the axes as required.
Figures, graphs and sketches should not be pasted in.

7.
Neat handwritten calculations and/or sketches may be appended at the
end of the homework.
These should be done on mech pads.

8.
In most cases, a conclusion or recommendation is appropriate in addition
to a numerical result.

9.
All citations MUST be properly referenced. WWW references are not acceptable.
